Abstract

Ecological safety of water intakes in urban water management systems and the creation of comfortable living conditions for people can be ensured only with a comprehensive solution to the problems associated with improving water quality when it is taken from the source, preserving biodiversity in the water body, protecting against blue-green algae, zebra mussel and mechanical pollution. The water intake technological complex as a part of the natural-technical system (NTS) specialized type “Natural water environment - Urban water management complex - Urban water supply system” (“NWE - UWMC - UWSC”), as the main multifactorial technogenic component, includes various types of hydraulic structures and protective devices interconnection, interaction and relationship (IIR), which ensure the environmental safety (ES) of the urban economy. The studies have established that the functional IIR between the structural elements of the “UWMC” in the composition of this NTS type “NWE – UWMC - UWSC” determines the generalized design and technological solutions, which determine the complex of protective measures to ensure the ES preservation of health and the urban population life quality. Based on the results of complex (theoretical, laboratory, full-scale) studies, constructive and technological solutions have been developed to preserve the diversity of ichthyofauna (juvenile fish, etc.) in the water body, to ensure the protection of the water intake bucket from bottom and suspended sediments, sludge and floating objects coming from the water body, from toxic blue-green algae and fouling with zebra mussel of structural elements and technological equipment as part of the urban water management complex. Functional sequence of IIR structural and technological solutions (STS-1, STS-2, STS-3) between themselves (Fig. 1) provides regulatory requirements for environmental safety.
